GEARING FOR WASHING-MACHINES.

Applicatidn filed september Specification of Letters Patent.

11, 190v. Serial No. 392,337.

Be it known that I, HENRY W. DARROW,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gearing for Washing- Machines, of which the following is a specification.

This invention comprehends certain novel and useful improvements in gearing and is designed particularly for imparting an alter- -iati rotar der 0 a was ng machine. v

The invention'has for its primary object an improved gearing which will impart to the clothes carrying cylinder an approximately complete revolution first in one direction and then in the reverse direction; while the driving shaft is being continuously rotated in but one direct1on;which will possess to a marked degree the charac teristics' of simplicity, durability, efiiciency, and economy as to the cost of construction and also as to amount of spacenecessar for its location and operation, and whic will permit the cylinder or drum to be read- With these and other objects'in view as will more fully appear as the" description proceeds, the invention consists in certain constructions, arrangements and combmati'ons of the parts t at I shall hereinafter fully describe and then point out the novel features in the appended claims.-

For a full understanding of-the invention, reference is to be had to the following description and accompanying drawings, in

which:

Figure 1 is a vertical transverse section of a washing machine embodying my improved earing; Fig. 2 is a detail transverse sectiona view of a portion of the gearing; Fig. 3 is a'detail face view of that portion ofthe gearing heads of the revoluble cylinder; Fig. 4 is a transverse sectional view of the washing machine, the section being taken in a plane close to that in which Fig. 1 is taken, but looking in the opposite direction. Fig. 5 is a detail view, partly in section of the sup.- porting bracket, for a portion of the gearmg; and, 6 is a detail perspective view of the sw" plate support that ,carries the driving gears.

Corresponding and. like parts are' referred motion to the revoluble cylinwhich is carried by one of the to in the followi in all the views 0 the drawings by the sam reference characters.

Referring to the drawings, the numeral 1 designates the body of a washing machine, and 2 the tank or trough which forms a portion thereof. 3 designates a lid or cover for the'said body portion of the machine.

ing drum 4 may be and preferably is coneads 5, and is journaled by means of the trunnions 6 in stirrups 7, the arrangement being such as to permit the ready withdrawal of the cylinder,'as clearly illustrated in the drawi s. The racket 8 is secured within the body ortion 1 of the machine, at oneend thereof and is preferably provided with an outwardly projecting tubular boss 9 in which the driving shaft 10 is journaled. This shaft may be rotated b means of crank wheel, or y power of any kind, according as the machine is constructed for family or commercial use, the invention being applicable to both. The inner end of the? driving shaft 10 carries a master pinion 11, which meshes with a pinion 12, and the latter said pinions 12 and 13 being j ournaled on and carried by a plate support 14., The said plate 14 is formed with an aperture 15 by which'it is swung from the same center as the actuating or driving shaft 10, being'preferably, slipped on said shaft preparato to the insertion of the latter in the tubular earing or boss 9 of thebracket 8.

The pinion 13 is preferably of double the. thiclmess of the pinions 11 and 12 so as to project beyond the plane of the said pinions a circularly extending series of ins 16 m jecting laterall from one of the eads o the cylinder 4. T e pins 16 are preferably carlled' by and form integral parts of an annular plate 17 secured to one head of the cylinder 4 y screws, rivets, or other fastening devices and preferably formed with one of the trunnions 6 for the cylin'der. In addition to the circular series of pins 16, the annulus 17 may be formed with circular outer and inner raised trackslS and 19, designed for a guiding and directing device in theform of a roller 20 which may be formed either as an integral part of the pinion 13 or as a\separate partsein turn meshes-with a pinion 13, both of the description and indicated The revoluble cylinder or clothes carrystructed entirely of sheet metal, with the a hand operable 11 and 12 and into meshing engagement with v element of the combination is also formed with two transverse channels or passages 21, as best seen in Fig. 3, said channels connecting together or establishing communication between the ends of the respective tracks 18 and 19, and separatin the ends of the'circular series of pins 16. oacting with these lateral assages 21 are gear shiftin tracks 22 whic are formed on the annu us 17 and which preferabl describe arcs of circles struck with the ast or end pins of the series as centers. Preferably, the swinging plate support 14 for the driving gears is ormed above its ivot or point of suspension with an upwar yprojectmg arm 23. The bracket 8 is provided with a laterally projecting flange 8,- and said flange is formed with a guide slot 24:, which accommodates the arm 23 and the ends of which constitute shoulders 25 arid 26 against which the arm 23 is adapted to abut to limit the movement of the swinging plate 14 in either direction.

In the practical operation, the shaft 10 has a continuous motion imparted to it in one direction. The motion of the said shaft 10 is imparted by its pinion 11 to the intermediate idler pinion 12 and thence to the pinion 13. This last meshes with the pins 16 and thereby imparts a rotary motion to the clothes carr ing cylinder 4. The continued motion of t e shaft 11 and rotation of the pinion 13 will bring the latter to one end of the circular series of pins 16, and the pinion 13 will then be directed laterally throu h one of the passages 21 so as to shift from the inner circle of pm to the outer circle, or vice versa, as the case may be, to impart a reverse motion to the cylinder without changing thedirection of.

rotation of the driving shaft 10, the plate support 14 being automatically swung or shifted at the same time. The roller or guiding device 20 is preferably provided, although I do not deem it an indispensable element, in order to more accurately guide the pinion 13 in its meshing engagement with the series of pins 16, because it is more practical to use it, as it tends to make the entrance of the pinion 13 into the circle of the pins, or ern't from the circles to the outer side thereof more positive and accompanied by less noise and with a minimum of friction; it also enables the use of a small aperture or lateral passage to provide for the shaft of the pinion from the inner circle to the outer, or vice versa, and consequently gives a greater percentage of revolution in the tragverse of the driven gear' element: Furthermore, the.

tracks 18 and 19, in combination with the guide roller 20 insure smooth? running and also prevent the driving gear from ever coming too close to the row of pins in'thedriven gear.

In addition to the above mentioned advantageous features, it will be seen from the foregoing description in connection with the accompanying drawin that I have provided means in a revolub e cylinder washmg machine whereby an alternating rotary movement may be imparted to the c linder b geari located entirely within t e mac e, whfie at the;v same time, such gearing occupies no more space than would a single driving inion and row of teeth or pins on onehead of the cylinder without the automatically reversing features. The shoulders 25 and 26 limit the movement of the plate 14 which swings from the same center as the driving shaft 10 and assists in making the caring positive or sure in its action and not %able to get out of order, the flange 8] also assisting in producing this advantage in that it extends around the arm 23 and maintains the plate 14 swinging in one plane and prevents it from swingin outwardly at 1ts lower end toward the pins 16 which would cause a bindin action and strain, and injure the arts. T -e cylinder 4 may be very readi y removed, it being only necessary in order to accomplish this to turn the same until the pinion 13 shall have been brought to the outer; side of the circular series of pins.

Manifestly my invention is not limited to the round pins shown in the accompanying drawings, nor to the other illustrated proportions, constructions, and arrangements of the parts, various changes being permissible within the purview of my invention, and within the scope of the following clair'ns.

Havin thus described the invention, what is claime as new is:

1. In gearing of the character described, the combination with a revoluble part and a support therefor, of a drivinggear element carried by the revoluble part, a drive shaft journaled in the support, a pinion adapted to mesh with the driven gear element and ar-. ranged to impart an alternating rotary motion thereto, a swinging gear support on which said plinion is. j-ournaled, means for supporting t e gear support with its ivot coincident with the axis of the drive s aft, said gear support being provided with an upwardly ro ecti n arm, and a bracket formed wit a gui e' slot accommodating said arm.

Wardly projecting arm, and a bracket formed with a guide slot accommodating said arm and with shoulders against which said arm is adapted to abut to limit the movement of the gear support.

3. In gearing of the character described,

the combination of a revoluble part and a support therefor, said support including journal bearings and the revo uble part being provided with trunnions removab y mounted Within said bearings whereby the revoluble part may be removed from its su port, of a driven gear element secured to sai revoluble part and embodying a circular series of pins and a raised track concentric with the series of pins, said gear element being formed with passages forming communication between the ends of the respective inner and outertracks, a drive shaft journaled in the support, a pinion mounted for meshing engagement with the series of pins, a guide roller movable with said pinion and adapted to travel along the said tracks alternately and to pass through the lateral passages from one track to the other, for the purpose specified, a driving connection between said pinion and the drive shaft, and means for supporting said pinion and guide roller, said supporting means being independent of the revoluble part whereby said part may be removed from its support upon the movement of the guide roller and pinion upon the outer track Without interference by the driven gear.

In testimony whereof I aflix my signature in presence of two witnesses.
